VSC7321 Description
Lansing™ is an advanced Ethernet MAC chip, allowing a system with a standard CSIX-64 host interface access to 10 trispeed (10/100/1000 Mbit/s) Ethernet ports. The 10 separate tri-speed MACs support both half-duplex and full duplex at 10/100 Mbit/s and full duplex at 1 Gbit/s. On-chip FIFOs capable of handling short-haul flow control are located between the Ethernet ports and the CSIX-64 interface.
